My tiny printer could not print the big top and bottom parts.

So I just split them. Reducing the storage space in the top, but sticking to the concept of stabilizing everything with continuous threaded rods.

The model can be printed with a Prusa Mini+ or BambuLab A1 Mini when rotated by 45°. Make sure the infill it set to cubic though because using rectilinear infill, the infill direction might align with the outer wall direction, reducing the parts strength.

Checkout the original project from @ChrisBorge for the other parts:
